Abstract: Management of subscriber identity modules is disclosed. A server apparatus manages, in addition to or instead of mobile network operators, by a service provider, subscriptions to wireless communication networks. The server apparatus maintains subscriber identity module-specific usage records. Each usage record comprises a quantity quantifying amount of data transferred with each subscriber identity module and a limit setting the maximum allowed amount of data transfer for each subscriber identity module. The server apparatus compares periodically the quantity in each usage record with the limit in the same usage record, and if the quantity in the usage record is within a predetermined margin of the limit in the same usage record, transmits, with the data communication interface, to the mobile apparatus, a command to limit data transfer speed of the subscriber identity module defined by the usage record.
